rssmenoamei'nean 1, isie; Seria1'hlm 813'791 To all whom it''may concernr Be it kncwnathat 1 ARON EETEfiSQNQaBilt'P zen of'the United States, residing at'whrca e, in the county of'Oo'ok' and State or Illinois, have invented certain new iise ful Im rovements in Wire Mattress Fabrics; of which the following-"is a speci-ficatiom My invention Tel'atestti'bd bott'oin spring supports andits object is to (Wercome a diff ficulty andan objectiorrthat is common to fabrics f this kind, namely, that when not stretched or held spread the links bind, or become wedged, or tangled out of their" normal relations.

The present invention provides arconsttuc tion, combination ofparts, on for-in of indi vidual links, which peiinits the' us'e of the structure as a whole as if it werecloth-in stead of wire links; {so that when throwniinto a heap" it will not Become a knotted or tan'glol mass: The: present improvement is therefore adapted to be used as canvaspr netting" which he rolled; on folded: up quickly in substantially the s'anie'way and be unrolled or straightened out by reason of the freedom oftlielinks to fall into their proper relative positions under the force of gravity alone.

I am aware that there are constructions which resist tangling up and which permit the structure, or wire fabric, to be rolled up on an axis parallel to the pivotal axes of the links, but the present invention attains the non-tangling result in a structure that, as a whole, is flexible from corner to corner as well as from side to side, and in a structure which does not sacrifice the greatest possible strength in the interest of the non-tangling object, or add elements for that purpose, or increase the cost of construction, or make more diflicult the process of construction.

With these general objects in view, the invention hereinafter described consists of the novel form of link, and in its combination with connected links described herein in detail, illustrated in the accompanying drawing, and more particularly defined in the appended claims.

In the drawingFigure 1 is a plan View of what may be termed a section or piece of wire fabric embodying my invention. Fig. 2 is a vertical section through several of the links. Fig. 3 illustrates the flexibility or relative movability of several connected links in dircctions other than those which are controlled by the jnlvotal movements of the links. Fig. 4 is a perspective View of one of the individual} links;

eis shcwn niostjclear ly in Fig. 4, each link is a singlepiiece of wire with its ends 2 and 3 side byfside, and forming three projections ranes-one of which consists of what may for convenience be called the initial leg- 4 leavingtheend' and loop 2 and ofthe final leg-omens whiclite'rminat'es in the end and loop 31 The othertwo projections are, substantially, endless loops 6 and 7 which are free or' o en their entire lengths from tip to point-of junction 8 with the other projections: 7 Starting at the'loopor eye 2 the link is formed by makingar ght angle bend' 9, then a return bend 10, another similar retlir nlbend 11; aright angle'bend 12 engag-. ingthebend 9, and, finally, a return bend which embraces a substantially straight or uninterruptedrun 14 of loops 6 and7, and endsin the legor run 5 and its loop or eye 3.

As shown in Figs. 1 to 3, the eyes, loops, pivot portions 2 and 3 are engaged with therein 14 on opposite sides of the return bond 13-, which serves not only to bind the projection or legs 4 and 5 to the projecfor legs 6 an'd 7', but alsotopi'e'vent the ends 2 and 3 or the legs 4 and 5 from moving along the run 14 or longitudinally of the loops 6 and 7.

Fig. 3 shows six of the individual links or units of Fig. 4 and in said Fig. 3 the six links are designated separately by the numerals 15, 16, 17 18, 19, and 20. Notwithstanding the restriction to substantially pivotal movement only of the engagements of loops or eyes 2 and 3 with the leg 14, the links, as shown, are given so much latitude in the Way of relative angular movement and positions that the junctions 8 of connected links may be brought together as in the case of links 17 and 20 by reason of the fact that each loop 6 and 7 is open or unob-' structed all the Way to said junction. When so brought together the interengaging loops 6 and 7 cannot bind or stick upon each other so. as to prevent their resumption of normal positions shown in Fig. 1 when one side or edge of the structure or fabric is grasped in the users hands and straightened out. In other words the fabric may be shaken out or straightened from a crumpled up mass in the same manner as a blanket or piece of cloth after it has been thrown into a heap.

The extended relative movements of loops I 6 and 7 of adjacent connected links will, as

s also indicated by the relations of the links the diagonal roll would be a little larger.

Such a handling of many of the heretofore provided structures would so badly; bind and entangle links and joints that only considerable expert labor could untangle or re- It will be noticed that there are no separate clips," bands or loop attachments to make joints or hold the same in proper relation, The bend 13,-which' also serves as 'a lateral stopfor the pivot eyes 2 and 3, is a smooth and firm support for-the run 14 of loops G and 7 against the strains imposed through arms 4 and 5, and'asthe eyes -2-and 3 of the latter are immediately adjacent to the loop or bend 13 there isno efiective bending strain upon the run 14 even with the load strain being wholly along the lines of the arms 4 and 5, which would not be possiblevin. practice where the strain is just as great longitudinally of the loops 6 and 7,

The bend 13 being, exclusive of the eyes 2 and 3 which may be made either first or last, the final bend, there is noobstaclein the way of a prior bend or formation in theway of anysubsequent bend or formation in the link, which makes the structure of the link orunit exceedingly simple as well as strong, there being no part which is capable of opening aside from the eyes 2 and 3, and

these may be entirely closed by welding or soldering if desired.

Having thus described my invention, I claim asnew and desire to secure by Letters Patent- 1. A link for a wire fabric, which consists of a single wire bent a certain distance from its initial end at right angles, then bent upon itselfto form an elongated loop extending to the right-angle bend first-mentioned and beyond said bend to form another similar, loop on the other side of the bend, and finally bent around said first-mentioned right-angle bend and the elongated loops and returning to its starting point, said starting point being the two ends of the wire, which ends are formed into eyes or loops adapted to engage the elongated loops of 'anadjoining link on opposite sides of the bend around the right angle bend.

12. Awire fabric-consisting of links each of which has three arms or projections, two of which form substantially one long loop and the third extends from the middle of said long loop at right angles thereto and consists of a right angle bend in said wire and a loop around the long loop, said third arm being the terminal runs of the wire lying side by side,or parallel to each other, and terminating in pivot eyes adapted to be corinected with the long loop of an adjacent lin r. I

i: In testimony whereof I have hereunto subscribed my name.
